- Introduce a global CSS utility `with-pastel-balls` in `web/src/index.css`, rendering pastel “blur balls” via ::before with CSS variables (`--pb1..--pb4`, `--pb-opacity`, `--pb-blur`) for easy theming. - Apply the utility to pricing header cards and skeletons: - `web/src/components/table/model-pricing/layout/header/PricingVendorIntro.jsx` - `web/src/components/table/model-pricing/layout/header/PricingVendorIntroSkeleton.jsx` - Remove per-component inline `linear-gradient(...)` backgrounds and redundant absolute-positioned decoration nodes to reduce duplication. - Dark mode: - Keep the same pastel palette (pink/lavender/mint/peach). - Increase visibility with `--pb-opacity: 0.36`, `--pb-blur: 65px`, and `mix-blend-mode: screen`. - No functional logic changes; UI-only. Lint passes. Affected files: - web/src/index.css - web/src/components/table/model-pricing/layout/header/PricingVendorIntro.jsx - web/src/components/table/model-pricing/layout/header/PricingVendorIntroSkeleton.jsx
